To all whom it may concern:

Be it known that I, Anrouso Hnnmo, a citizen of Chile, S. A., and aresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in ReversibleTypewriter-Type, of which the following is a s ecification.

he principal purpose of this invention is to provide novel and racticalmeans for enlarging the range an $00 e of characters on any type barmachine wit out increasing the number of key levers or changing themachine in any manner other than substituting improved type bars forcertain of the common style and the use of special type reversibly andremovably engaged thereto.

Another object is to provide a form of type, and typebar head used inconnection therewith, that conform to the standard type of the machinein proportions, dimen- SlOIlS weight and all essential characteristics,but which are so arranged as to double the character capacity of themachine.

A further object is in the provision of such devices in forms whichpresent no difficulties in manufacture, assemblage or operation, thetype and bar being essentially simple and cheap, strong and durable, andeasily reversed when desired by the fingers.

These objects are attained by the novel construction, combination andarrangement of parts hereinafter described and shown in the accompanyingdrawings, forming a material part of this disclosure, and in which 2-.liigure 1 is a front elevational view of a type made in accordance withthe invention, as applied to a conventional form of type Fig. 2 is aside elevational view thereof.

Fig. 3 is a perspective viewof the same showing the type carryingelement in a partially reversed position.

Fig. 4 is a perspective view of the type block in detail looking fromthe under side.

Fig. 5 is a perspective view of the type back retaining means in detail.

Fig. 6 is a side elevational view of the type block as applied to anUnderwood type bar, drawn to a reduced scale.

Stated in general terms, the invention consists in forming an open orhollow head on any st le of type bar, the head conforming in thic nesswith the width of the type block and drilling the head diagonally atapproxi mately forty-five degrees from its face.

The type block,which is of integral construction, presents two branchesdisposed at right angles, one of the branches bearing on its outer facethe number of characters carried by the ordinary type of the machine; asfor instance in a single shift typewriter, each type block carries twocharacters, as the upper case or capital and lower case or small letter,as the N and n shown.

The other branch carries in a similar man ner any two other characters,as the English pound sterling and. paragraph marks, although obviouslyany preferred characters may be used.

Extending centrally between and from the junction of the branches is acylindrical stem suited to engage the drilled hole in the type bar headand provided near its end with an annular recess in which is receivedthe forked end of a curved fiat spring disposed within the opening inthe head and having its opposite end shaped to partially encircle thestem, bearing against the inner wall of the opening.

Thus the spring tends to draw the branches of the type block snuglyagainst the upper and front faces of the type bar head, but permits thestem to be withdrawn in reversing the relative position of the typeblock branches and it can be bodily removed in dismounting the block.

' Referring now more particularly to the drawings in detail, the numeral10 designates the shank of a conventional type bar, such for instance asis used in the Remington machines, provided with a guide spur 11 andhaving a thickened head 12 extending to the front.

In Fig. 6, the Underwood type bar 10 is formed with a like head and itis to be noted that these heads, when the type block is in position,extend outward precisely the same distance as those of standardconstruction.

The lower, front corner 14 of the head is square while the upper frontcorner 15 is curved, presenting two. flat faces 16 and 1.7 at a rightangle to each other, the central. portion of the head being removed,forming a diagonally disposed, oblong opening 18, reducing weight andproviding space for purposes farther on apparent.

' A hole 19 is drilled through the curved" upper corner 15 midway in thethickness of the head, the hole bisecting the opening 18 and extendin asat 19, into, but not through, the ower rear corner of the head holes 19end 19 e id when on e near its junction with the bar, the axis of thehole being at forty-five degrees from the seating surfaces 16 and 17.

The type block consists of two elongated rectangular members 20 and 21,alike in all their dimensions and bearing on their ex;- posed outerfeces type characters as indicated Thus for machines h* 7 actor on. eachkey leren one C appear on each face; 7' chine is used two ch: doubleshift machine 'llijeo each face are reouired.
